Plain 100M/100K Endurance Runs

Plain, WA
100 KM |
100 Miles
Plain is an unmarked, self-supported trail run on the east side of the North Cascades in beautiful Washington State. Close to Leavenworth and Lake Wenatchee, this race is for those looking for more challenge than that provided by the typical fully supported trail race. With approx. 21,000 gain and a high point of 7000 ft, the event is very well monitored with 6 checkpoints and excellent participant tracking. All proceeds are donated to local non-profits such as military transition groups and our local Search and Rescue organization.

100 Miles
The Plain 100 consists of two separate lolli-pop loops. The race is a self-supported format which means no aid stations - only SAR checkpoints. The runner needs to be self-sufficient for each of the two loops with one re-supply point at 100K.
